Memory
The category is display-only which is determined by POST (Power On
Self-Test) of the BIOS.
Base Memory
The POST of the BIOS will determine the amount of base (or
conventional) memory installed in the system. The value of the
base memory is typically 512K for systems with 512K memory
installed on the motherboard, or 640K for systems with 640K or
more memory installed on the motherboard.
Extended Memory
The BIOS determines how much extended memory is present
during the POST. This is the amount of memory located beyond
1MB in the CPU's memory address map.
Other Memory
This refers to the memory located in the 640K to 1024K address
space. This is the memory that can be used for different appli-
cations. DOS uses this area to load device drivers to keep as
much base memory free for application programs. Most use for
this area is Shadow RAM.
Total Memory
System total memory is the sum of basic memory, extended
memory, and other memory.
